window.onerror does not work in Safari

Posted on June 7, 2007 by James McParlane 
// Declare Error Handler
function oops() 
{
  alert ('Error!');
  return true;
}
// Assign to global error handler
window.onerror = oops;
// Trigger an error
x.y.z();

This does not work, and it makes me sad.

Updated – removed syntax error from example

    As far as I can tell, this is still the case, and still frustrating…

    Any word on whether it might someday change?

    I pasted your example into the latest version of Safari and it appeared to work…

    But alas, there’s a bug in your example – it should be

    window.onerror = oops

    and it’s still not working… 😦

    Actually, window.onerror is not part of any specification

    Four year later, and Safari still doesn’t have window.onerror, even though it is now part of the HTML spec.
    As a kludgy work-around, I’ve put together genericOnError, which emulates window.onerror for Safari and Opera.
    It won’t make you happy, just a little less sad.
